R related issues; use ‘R:’ as a prefix in your search termAssigning things in R is very straightforward:
<-For example, if you assign the value 100 (an element) to object a, you would type
a <- 100
Calling things in R is also very straightforward:
For example, we assigned the value 100 to object a. To call object a, we would type
a
## [1] 100
This is why we use R-Studio.
